This piece of software is probably the greatest technological achievement United Kingdom has ever given to this world ;-) Anyway, DVD Decrypter is really the only tool we need in our guide, provided that your ASPI settings are OK already.
Select ISO mode
This step is to change the ripping mode. From Mode menu, go to ISO selection and select Read.
This is pretty much what you see after the mode change. This view gives you certain information that is extremely important for us.
On the right-hand side you see various information about the DVD-Video itself. The only thing that really matters here is the DVD size. This has to be less than 4,718,592,000 bytes, otherwise the movie wont fit on a blank DVD.
Select the destination
From the destination box, you have to select a filename and directory where to store the ISO image the DVD Decrypter will create for you. This directory has to have at least the same amount of free space as the DVD's size is.
Copy the DVD to harddrive
After setting the destination filename, simply click the copy symbol in bottom of the window and DVD Decrypter will start ripping the movie and creating a DVD image file to your HDD.
Burn the image to DVD
After the ripping process has finished, you simply go to Mode menu again and select Write under ISO selection.
Now you need to select the image file from the harddrive. Click the source filename in DVD Decrypter's window and it pops up a file dialog. Note that if you have other than NTFS filesystem, you might have multiple files on your harddrive now, one of them is with extension .DVD and this is the file you need to select -- if you have NTFS, select the only file you see in the directory you selected and click OK.
Ready to burn
Now simply check that all the settings are correct. Use test if you want, use burn-proof if your drive supports it, change write mode to DVD, keep data type as Mode 1/2048 and choose write speed according to your drive's specifications. Then, click the copy symbol in bottom of the window and wait while the disc burns.
Now you should have a DVD-Video backup that can be viewed with most modern stand-alone DVD players -- just remember that not all DVD players play these discs. Compatibility issues can be caused by the burning speed, the DVD player or by the DVD media. Should things go wrong the first thing to do is make sure you have followed our guide literally. Next try the process with some other DVD media -- the quality of the discs really makes a huge difference in DVD-Video use.
